3D Prints

have decided to use my 3d printer again after a while (ender 3 v2) and i bought some new pla filament, when starting new build it failed.
the supports were very flaky they looked like it was just extruding mid air, even though i repeatedly made sure the build plate height was good,
the supports didnt support anything so nothing was built.
when i tried another build that didnt require supports my 3d printer would stop printing half way through (i dont know exactly what happened between the time it stopped printing as i wasnt there)
this isnt a one time issue i have tried for a week my printer is on 24/7 trying again and again but still the same problem. stopping mid print and if supports are needed then it cant even start.
sometimes the pla print is smooth sometimes it isnt.
i print at 210'c and have tried 195'c but still nothing changes, i have 55'c-65'c build plate temp. i use cura btw. i am certain there isn't a clog in my print because it works fine when i start another print but again half way through it decides to stop printing again. i have messed around with extrusion and it still hasn't changed anything
the picture of the flakes it literally the supports it sounds ridiculous but that is literally the supports
also as you can see in those 2 unfinished pieces of plastic when it starts to stop printing it starts becoming gritty around the edges you can see spikes coming out
with all of these issues i have not managed to make a full print in this whole week with my printer on every night. every time i wake up and it has stopped half way through with many flakes everywhere
when i start printing it prints on the build plate then gradually goes up and makes thing worse
in this picture i stopped the build just before it started moving up so this is basically the first layer of supports
non of this explains why my prints stop mid way through.

actually would that bottom layer even print, maily i dont want the hexagons to connect, becuase i dont remember that being there in my other prints

Still a lot of mesh problems...
A lot of faces with wrong normals and the walls of the spherical things in the middle have no thickness.
I think there are plenty of tutorials out there about how to use Blender together with 3D-printing...
At least you should activate the "3D printing tools" plugin and always check the model before exporting it.
And be absolutely sure that there are no doubled vertices and no overlapping faces and all that... Basically - always do all the "standard" checks for a good mesh topology...
Good luck!
just 1 more thing how can i change the settings so this thing isnt at the bottom of my build. (the circle at the floor of the build

thanks i think i have done it all and ready to print thanks for the help (both of you)

hexagon test rings.stlsorry i forgot to add the flooring to that this is my final file, it still does the same thing though (closing the sphere)

once again i have a problem. i put the second part onto my design and it seems to close 2 of the spheres near the last few layers how can i stop this i just want 2 spheres in the middle

Oh I found this:
if using blender - here's how to fix your model
I went into edit mode with the object in Blender 2.83 and pressed "a" which selects all faces / vertices / edges, depending on what select mode you are in. The entire object should be highlighted. I then went to "Mesh" (see images), went to the "Normals" section, and selected "Recalculate Outside". This probably will not fix any edges that are not merged, but it will fix the faces that are inverted on the object.thank you so much, been a lot of help.

sorry this is only the stl i cant but the .blend file in. if there is any you want me to export it as tell me

Hello? Still need help? I'm going to guess your normals are backwards for those inner walls. And that means you are probably using sketchup. Am I close?
i am using blender but where do i use the file options

so im pretty new to 3d printing and ive made this row of circles (in shapes of hexagons) in blender, when i put it into cura it closes the circles close to the to when it finishes. i want the entire thing exactly as it looks like on the prepare tab picture i included (hole from one end to the other). also when i try to put in 1 hexagon at a time it still fills in the inner space, couldnt find anything online to fix this. please dont use any big technical words im new to this world.
3d prints are coming out horribly

also i forgot to add that it has stopped extruding all of a sudden when on the supports, the extruder just reverses. i dont know if this is because its printing mid air.
